YM's YSF-4 is a precision-engineered, single hydraulic valve designed for critical aviation sensor systems. It provides reliable, high-speed flow control in demanding environments such as drone and aircraft engine hydraulic circuits. Manufactured with the same stringent standards as our Military Metal Sealing Relay series, the YSF-4 valve ensures exceptional durability, minimal leakage, and consistent performance under extreme pressure and temperature variations.
Core Features & Technical Advantages
This valve integrates seamlessly into complex systems, much like a PCB Signal Relay integrates into a control board. Its design focuses on precision and reliability.
- Rapid Response & High Precision: Features an ultra-fast action time of ≤3ms, enabling real-time hydraulic control crucial for flight stability and engine management.
- Military-Grade Sealing Integrity: Employs advanced sealing technology with an extremely low leakage rate (≤1x10⁻³ Pa·cm³/s), ensuring zero fluid loss and system safety, a standard derived from our Sealed magnetic Latching Relay production.
- Lightweight & Robust Construction: Weighing less than 3 grams, it minimizes impact on the overall weight of aircraft systems while maintaining structural strength under high pressure.
- Superior Electrical Insulation: Provides excellent insulation resistance (>500 MΩ under normal conditions), preventing electrical interference in sensitive sensor lines, similar to the isolation offered by our Solid State Relay products.
- Extended Operational Life: Engineered for high-cycle durability (rated for 1x10⁶ operations under specific loads), matching the longevity expected from critical components like an Industrial Power Relay.

How to Integrate the YSF-4 Valve: A Step-by-Step Guide
Proper integration is vital for system performance and safety. Follow these key steps.
- System Compatibility Review: Verify that your hydraulic system's pressure, fluid type, and electrical driving signal (e.g., pulse width of 10-50ms) are compatible with the YSF-4's specifications.
- Pre-Installation Inspection: Check the valve and its ports for any physical damage or contamination before connecting it to the hydraulic line and Aviation Sensor.
- Precise Installation: Connect the valve into the designated sensor hydraulic line. Ensure all fittings are secured to the torque specifications required for your aviation platform to prevent leaks.
- Seal Verification Test: Conduct a pressure and leak-down test on the installed assembly to confirm the sealing integrity meets the ≤1x10⁻³ Pa·cm³/s standard.
- Functional & System Integration Test: Power the valve with the correct coil voltage and integrate it with the overall control system. Perform a full functional test to validate response time and control accuracy, similar to testing a circuit with a DPDT 8Pin 27V Relay.
Primary Application Scenarios
The YSF-4 valve is essential in applications where precise hydraulic control directly impacts system performance and safety.
- Unmanned Aerial Systems (UAVs): Controls hydraulic pressure for flight control surface actuators or landing gear sensors in advanced drones.
- Manned Aircraft & Helicopters: Manages hydraulic flow for engine sensor lubrication systems, fuel control units, or environmental control system sensors.
- Aircraft Engine Test Rigs: Used in ground-based testing equipment to precisely simulate and control hydraulic conditions for engine sensor calibration.
